General annotation (Comments)
| Function | Cation channel with high affinity for sodium, which is gated by extracellular protons and inhibited by the diuretic amiloride. Generates a biphasic current with a fast inactivating and a slow sustained phase. In sensory neurons is proposed to mediate the pain induced by acidosis that occurs in ischemic, damaged or inflamed tissue. May be involved in hyperalgesia. May play a role in mechanoreception. Heteromeric channel assembly seems to modulate channel properties. Ref.7 Ref.9 Ref.14 |
| Subunit structure | Homotrimer or heterotrimer with other ASIC proteins By similarity. Interacts with STOM, LIN7B, MAGI1 and GOPC By similarity. Interacts with DLG4 and ASIC2. Ref.2 Ref.17 |
| Subcellular location | Cytoplasm By similarity. Cell membrane; Multi-pass membrane protein By similarity. Note: In part cytoplasmic in cochlea cells By similarity. Cell surface expression may be stabilized by interaction with LIN7B and cytoplasmic retention by interaction with DLG4. Ref.11 Ref.17 |
| Tissue specificity | Expressed in sciatic nerve and dorsal root ganglion (at protein level). Expressed in sensory neurons of dorsal root ganglion. Expressed in Golgi interneurons in the granular layer. Also found in superior cervical ganglia, spinal chord and brain stem. Ref.1 Ref.3 Ref.5 Ref.11 |
| Developmental stage | Expression is first detected at E15.5. Strongly expressed perinatally. Ref.12 |
| Induction | Transcriptionally regulated by the proinflamatory mediators nerve growth factor, serotonin, interleukin-1 and bradykinin. Up-regulation upon tissues inflammation is abolished by anti-inflammatory drugs. Ref.6 Ref.7 Ref.8 Ref.10 Ref.12 Ref.13 |
| Domain | The PDZ domain-binding motif is involved in interaction with LIN7A, GOPC and MAGI1/BAIAP1 By similarity. |
| Post-translational modification | Phosphorylated by PKA By similarity. Phosphorylated by PKC. In vitro, PRKCABP/PICK-1 is necessary for PKC phosphorylation and activation of a ASIC3/ACCN3-ASIC2/ASIC2b channel, but does not activate a homomeric ASIC3/ACCN3 channel. Ref.16 |
| Miscellaneous | Potentiated by FMRFamide-related neuropeptides By similarity. Sensitized and potentiated by NPFF and NPSF. Regulated by lactate and Ca2+. Specifically inhibited by APETx2, a sea anemone toxin. Inhibited by anti-inflammatory drugs like salicylic acid. |
| Sequence similarities | Belongs to the amiloride-sensitive sodium channel (TC 1.A.6) family. ASIC3 subfamily. [View classification] |
